 a material outlet, in communication with the confluence cavity and configured to discharge a first material sheet comprising the elastic polymer material disposed on a first side of the first material sheet and the binding material disposed on a second side of the first material sheet; 
   and   a pressing device configured to laminate the fabric sheet to the second side of the first material sheet.   
     
     
         2 . The manufacturing apparatus according to  claim 1 , wherein the pressing device comprises a first roller and a second roller configured to convey the first material sheet and the fabric sheet therebetween. 
     
     
         3 . The manufacturing apparatus according to  claim 2 , wherein at least one of the first roller and the second roller comprises a working surface made of a metallic material. 
     
     
         4 . The manufacturing apparatus according to  claim 3 , further comprising:
 a cooling system comprising a cooling pipeline,   wherein the first roller comprises a working surface made of a metallic material, and the cooling pipeline is disposed in the first roller.   
     
     
         5 . The manufacturing apparatus according to  claim 3 , further comprising:
 a cooling system comprising a cooling pipeline,   wherein the second roller comprises a working surface made of a metallic material, and the cooling pipeline is disposed in the second roller.   
     
     
         6 . The manufacturing apparatus according to  claim 2 , one of the first roller and the second roller comprises a working surface made of an elastic material. 
     
     
         7 . The manufacturing apparatus according to  claim 1 , wherein the binding material comprises a reactive adhesive. 
     
     
         8 . A method for manufacturing a sheet, the method comprising:
 receiving a supply of an elastic polymer material and a binding material and a fabric sheet; and   forming a material sheet comprising:
 a first layer comprising the elastic polymer material, 
 a second layer comprising the binding material, 
 an intermediate layer, between the first layer and the second layer, the intermediate layer comprising a mixture of the elastic polymer material and the binding material, and 
   a fabric layer comprising the fabric sheet bonded to the second layer.   
     
     
         9 . The manufacturing method according to  claim 8 , wherein the material sheet is a second material sheet, the method further comprising:
 prior to forming the second material sheet: forming a first material sheet, the first material sheet comprising the first layer, the second layer, and the intermediate layer;   wherein the forming the second material sheet comprises pressing the first material sheet and the fabric sheet such that the first material sheet is bonded to the fabric sheet by means of the second layer of the first material sheet to form the second material sheet.   
     
     
         10 . The manufacturing method according to  claim 9 , further comprising:
 cooling the first material sheet using a pressing device.   
     
     
         11 . The manufacturing method according to  claim 8 , wherein the binding material comprises a reactive adhesive. 
     
     
         12 . A sheet, comprising:
 a covering layer comprising:
 a first layer comprising an elastic polymer material, 
 a second layer comprising a binding material, and 
 an intermediate layer between the first layer and the second layer, the intermediate layer comprising a mixture of the elastic polymer material and the binding material; and 
   a fabric layer bonded to the binding material.   
     
     
         13 . The sheet according to  claim 12 , wherein the sheet is made by pressing the covering layer and the fabric layer. 
     
     
         14 . The sheet according to  claim 12 , wherein the binding material comprises a reactive adhesive.
